Fig.3. Fig.4. There are three principal elements of a laser, which are (1) an energy pump, (2) an optical gain medium, and (3) an optical resonator. These three elements are described in detail below for the case of the HeNe laser. (1) Energy pump. A 1400 V high voltage, DC power supply maintains a glow discharge or plasma in a glass tube containing an optimal mixture (typically 5:1 to 7:1) of helium and neon gas, as shown in Fig. 1 and indicated in the diagram of Fig. 2. The discharge current is limited to about 5 mA by a 91 k W ballast resistor.
